Lessentor

The lessentor bark, brown-orange in color, has the particularity of being extremely smooth. The preparation with a sweet taste increases the reflexes. Some experienced rogues like to use the lessentor on high-risk exploration missions.
A decoction of lessentor grants a +2 bonus to initiative and Dexterity saving throws for 1 minute. Several potions do not stack bonuses, and lessentor has no effect on other Dexterity checks.
